Hi Jessica,

I understand your expectation, unfortunately, currently that icon is only used on new modules you create after changing it. If you feel it should apply to existing modules on the same application, I suggest you check the Ideas area of this site and search for an idea on this and upvote it... if you cannot find one, create your own so others are aware and may vote for it as well :-)

Now, how can you fix it:

• On your module definition (open the module and select it from project tree) you can change its Icon (a smaller version of your Application Icon, typically with a resolution of 196x196 pixels would be ideal).
• On the Interface tab, scroll down to Images, expand it and replace the Logo image with the one you used for the Application Icon (again, default resolution seems to be 196x196 pixels).
• Finally, on the Data tab, scroll down to Resources, and you will find a favicon.png file that you should also replace with a small version of the application icon in PNG format (default resolution seems to be 43x43 pixels)

That's it, hope it helps!
